Fix PopupBlockerBrowserTest.WindowFeatures when Refresh is on.

Refresh is a project to redesign the core UI, primarily the tapstrip's
height and shape. The result is that popup windows are slightly taller
because of some added frame padding. This patch makes the test
checking for the height of the window more lenient.
